PLEASE HELP!!! Describe in detail what you expect for the changes in enthalpy, entropy, and free energy when a sample of liquid evaporates. How does temperature affect these changes?

    when liquid evaporates we know that it's going from a liquid to a gas therefore going from an ordered state to a more chaotic disordered state meaning the entropy which is the measure of order, goes up. Since this is a spontaneous reaction at high temperatures and non spontaneous at low temperatures and free energy is negative for spontaneous then we can say at high temperatures free energy is negative and at high temps and positive at low temps. Also since evaporation requires energy to evaporate the enthalpy is positive.

    Determine the rate law, including the values of the orders and rate law constant, for the following reaction using the experimental data provided. A + B yields products Trial [A] [B] Rate 1 0.15 M 0.12 M 1.3 × 10-2 M/min 2 0.30 M 0.12 M 2.6 × 10-2 M/min 3 0.15 M 0.24 M 5.2 × 10-2 M/min

    Ya I checked through it since I didn't want to post a stupid link but I think that I would just confuse you more if I tried to explain and I didn't want to do that! So hopefully that helps if it doesn't it doesn't I highly suggest the Khan Academy videos on YouTube they start out with basics and explain each step they helped me out when I did this stuff!
